Aqueous coating composition with corrosion resistant thin-coat aluminum pigments, method for production and use thereof

An aqueous coating composition, comprising at least one water-compatible film-forming agent and aluminum pigments that are provided with at least one inorganic anti-corrosion layer,

• characterized in that
• the aluminum pigments, which are rolled out by mechanical shaping, have a lamellar structure and the thickness of said aluminum pigments, plus that of the at least one inorganic anti-corrosion layer, averages less than 160 nm;
• said anti-corrosion layer consists essentially of silicon dioxide, wherein a silicon dioxide surface of said layer is coated with silanes;
• and
• an aspect ratio, which is calculated from the ratio of an average longitudinal extent to an average thickness of said aluminum pigments provided with the at least one inorganic anti-corrosion layer is more than 200.
